Ignition Coil Replacement

Meet some of our expert Mercedes-Benz mechanics

Rocco came to my home to check out my car since it would not start. I did not want to go through the hassle of having to tow it to a repair shop and wait around. I had a problem with my starter. With repairs like this you would think you'd have to go to a repair shop but I'm relieved I was able to have it fixed at my home from someone professional. He came and checked out my problem (which took less than an hour), provided an estimate along with how much time/labor would be involved and the next day came and made the repair. And I was able to save time without waiting around for other customers and cars ahead of mine like at a shop. I'd definitely use the service and call him again in the future :)

All about Ignition Coil Replacement

Ignition coils transform low voltage electrical power 12 volts D.C. to high voltage current 50,000 volts D.C. or higher. The spark generated by the ignition coil ignites the fuel and air mixture in the engine that enables the car to start and run smoothly.
If an ignition coil is not working properly, no spark will ignite the air fuel mixture, causing a misfire. A bad ignition coil can severely damage the engine or catalytic converter.
If your car is equipped with “coil over plugs,” then it is recommended that you replace the spark plugs. If your car uses a single coil for the ignition system, it is not necessary to change the spark plugs.

An ignition coil turns low voltage into high voltage, which is then used to ignite your vehicle. After the ignition coil has converted the low voltage into high voltage, it creates a spark, which lights the fuel, and powers the engine. This small explosion is responsible for turning on your engine, and for keeping the engine running. When the ignition coil is damaged, it is unable to create this high voltage spark, and your engine will have a hard time running, or may not run at all.
